Grapevine plant named ‘Sugrafortynine’

ABSTRACT

A new and distinct variety of grapevine ‘Sugrafortynine’ is characterized by a very early harvest date, the production of a medium-large sized, black, narrow elliptic berry and a very large bunch size. The berries of ‘Sugrafortynine’ are moderately firm.

Latin name of the genus and species claimed: Vitis vinifera.

Variety denomination: ‘SUGRAFORTYNINE’.

BACKGROUND AND SUMMARY OF THE INVENTION

This application relates to the discovery and asexual propagation of anew and distinct variety of grapevine, ‘Sugrafortynine’, as hereindescribed and illustrated. The new variety was first selected as breedernumber ‘GR313B’ by Terry A. Bacon in Wasco, Kern County, Calif. in July2012. The variety was originated by controlled hybridization.

The new variety ‘Sugrafortynine’ is characterized by a very earlyharvest date, the production of a medium to large sized, black, narrowelliptic berry and a very large bunch size. The berries of‘Sugrafortynine’ are moderately firm.

The seed parent is the varietal selection ‘04035-204-488’ (unpatented)and the pollen parent is ‘Sugrathirteen’ (U.S. Plant Pat. No. 10,434).The parent varieties were first crossed in May 2010. The date of firstsowing was March 2011, and the date of first flowering was May 2012.

The new variety ‘Sugrafortynine’ was first asexually propagated inDecember 2012 in Wasco, Kern County, Calif., by Terry A. Bacon usinghardwood cuttings.

The new variety ‘Sugrafortynine’ differs from its seed parent‘04035-204-488’ (unpatented) in that the new variety ‘Sugrafortynine’has a larger cluster size at about 650 g compared to 450 g for‘04035-204-488’. The new variety ‘Sugrafortynine’ also differs from itsseed parent ‘04035-204-488’ in that the new variety ‘Sugrafortynine’ hasa larger berry size at 5 g compared to 2 g for ‘04035-204-488’.

The new variety ‘Sugrafortynine’ is similar to its pollen parent‘Sugrathirteen’ (U.S. Plant Pat. No. 10,434) in appearance but the newvariety ‘Sugrafortynine’ begins ripening about 18 days earlier, on June28 compared to July 17 for ‘Sugrathirteen’.

The new variety ‘Sugrafortynine’ has a berry color that is similar tothe USDA variety ‘Summer Royal’ (unpatented), but the new variety berryshape is narrow elliptic, compared globose for ‘Summer Royal’. The newvariety ‘Sugrafortynine’ has a larger black berry compared to a smallerred berry from ‘Flame Seedless’ (unpatented), and the new variety berryshape is narrow elliptic, compared globose for ‘Flame Seedless’.

The new ‘Sugrafortynine’ variety has been shown to maintain itsdistinguishing characteristics through successive asexual propagationsby, for example, cuttings and grafting.

Variations of the usual magnitude from the characteristics describedherein may occur with changes in any of a variety of factors such asgrowing conditions, irrigation, fertilization, pruning, management andclimatic variation.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustration shows typical specimensof the foliage and fruit of the present new grape variety‘Sugrafortynine’. The illustration shows the upper and lower surfaces ofthe leaves and exterior and sectional views of the fruit. Thephotographic illustration was taken shortly after the fruit was pickedand the colors are as nearly true as is reasonably possible in a colorrepresentation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small lettersignify that the name of that color, as used in common speech, is aptlydescriptive. Color names beginning with a capital letter designatevalues based upon The R.H.S. Colour Chart, published by The RoyalHorticultural Society, London, England, 1986.

Many of the descriptive values in this specification are based on andconform to those set forth by the International Board for Plant GeneticResources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997,which was developed in collaboration with the Office International de laVigne et du Vin (OIV) and the International Union for the Protection ofNew Varieties of Plants (UPOV).
